Ask HN: Is implementation of encryption by WhatsApp reliable?

[stereotactic]

In the privacy fiasco of Zoom, I am looking for documentary proof of WhatsApp encryption implementation. I want a documentary evidence that WhatsApp encryption is poorly implemented or it is easier for Facebook to ferret out the conversations. )Please also recommend alternative secure messenger for healthcare)

You can't be sure the app is secure unless it's audited by a third party, open source, and compiled by you. I believe there are a few alls with these qualities, but I don't know what they are.

There are messaging companies that specifically comply with health care laws, which is a separate issue entirely.

Thanks and appreciated. Agreed.

WhatsApp uses Signal's encryption but it's hard to verify how much they changed. While signal provides a way to check that using cross-compiling reproducible build even for server code you can verify.

I agree about it too. Isn't that Skype and other Microsoft products offer the same protocol?
